The present invention relates to air inflation beds, and particularly to a quick draining air valve of an air inflation bed which can drain air in the bed in emergency.

Referring to
An air valve 94 with three holes is connected to an air compressor 93. The air inflation tube 94a is retained with high pressure air and is communicated with the lower air chambers 91b and the air inflation strips 92. The right and left air inflation tubes 94b and 94c are connected to the upper air chambers 91a. Furthermore, by an air distributor in the air valve 94, the releasing of air is controllable.
However when it is desired to perform cardiopulmonary resuscitation for an emergency, the residue air in the bed must be drained out. Conventionally, the pipes connected to the valve 94 is removed so that air in the bed is released naturally, but it is too slow to perform the cardiopulmonary resuscitation. The time required is about one minute. Thus it is possible that the patient can not be rescued.
Accordingly, the primary object of the present invention is to provide a quick draining air valve, wherein the quick draining air valve has a first valve and a second valve. In emergency, a cover plate is opened so that air guide hole of the air guide plate are opened. The high pressure air is drained out from the air guide holes of the air guide plate so that the residue air in the first tubes connected to air inflation tubes pass through the air channels are driven by the high pressure air drained from the air holes of the second valves so as to be drained out of the second valve through the air guide holes so as to reduce the draining time of the air cushion bed.
The quick draining air valve of the present invention can be used to an air inflation bed. In emergency, the cover plate is opened for draining air quickly and thus the CPR can be performed to the patient.
To achieve above objects, the present invention provides a quick draining air valve, comprises a first valve having an air inlet device for inputting high pressure air; a second valve having at least one channel which is extended to a surface of the second valve; a distal end of the channel extending with a tube which is connected to the air inflation tube; the second valve being connected to the first valve so that high pressure air enters into the tube through the channel and then into the air inflation tube; and a cover plate being openable, high pressure air providing by the first valve being drained out with a high speed from the second valve; by the channel of the second valve, residue air in the air inflation tube connected to the tube of the second valve is drained out from the second valve.
Furthermore, in the present invention, the cover plate is pivotally connected to an air guide plate and is buckled to a buckling block of the air guide plate by using a buckling plate so that the cover plate can be opened conveniently.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
With referring to
A first valve 10 has an air inlet device 11 which is connected to an compressor for providing air. An interior of the first valve 10 has an air distributor 14 which is driven by a motor 12 (referring to
A top of the second air hole 10b has a pair of buckling grooves 23 for buckling the connecting block 13 of the first valve 10 so that the first valve 10 and the second valve 20 are combined tightly, as illustrated in
An air guide plate 30 is fixed to a bottom of the second valve 20 by using screws 31 for sealing the first channel 21a, second channel 21b and third channel 21c. A bottom of the air guide plate 30 is formed with recess 32. A recess surface of the recess 32 is formed with a first air guide hole 30a, a second air guide hole 30b and a third air guide hole 30c which are aligned to the first air hole 20a, second air hole 20b and third air hole 20c of the second valve 20. An upper side of the first air guide hole 30a is extended with a guide tube 35 having a notch 351. The guide tube 35 extends into the first channel 21a of the second valve 20. A distal end of the guide tube 35 is near the first air hole 20a of the second valve 20. Two sides of the air guide plate 30 are installed with a pivotal groove 33 and a buckling block 34, respectively.
A cover plate 40 has a pivotal seat 41 at one side thereof for pivotally connecting the pivotal groove 33 of the air guide plate 30 so that the cover plate 40 is rotatable along the pivotal seat 41. Besides, another side of the cover plate 40 opposite to the side installing the pivotal seat 41 is installed with a buckling plate 42. When the cover plate 40 covers upon the air guide plate 30, the buckling plate 42 is buckled with the buckling block 34 so that the cover plate 40 is steadily retained. A top surface of the cover plate 40 is formed with a protrusion 43. When the cover plate 40 is covered, the protrusion 43 exactly enters into the recess 32. A periphery of the protrusion 43 is enclosed by an air-tight washer 44.
Referring to
In emergency, as illustrated in
Since the air guide plate 30 covers the first channel 21a, second channel 21b and third channel 21c of the second valve 20 so that the effect of high pressure air driving the residue air is promoted. Moreover, if the air guide plate 30 is not used, the cover plate 40 air-tightly covers the first channel 21a, second channel 21b and third channel 21c of the second valve 20 directly. The draining speed of the residue air can be increased.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
